Error message: License is not valid.

In some countries you may see the following error message when you try to activate a license key: "License is not valid. Sometimes copy+paste from an email client introduces unexpected whitespace. Please try to enter the key manually."

How to fix it

  1. Open the smartpls.ini file which is located in the SmartPLS installation folder with a text editor. (Note: You need to run the text editor as Administrator.)

  2. Add a line containing -Duser.language=en after -vmargs so that it looks like:

...
-vmargs
-Duser.language=en
-DcheckForUpdates=true
...

  1. Save the file, launch SmartPLS and enter your license key
